Request InfoMcPHERSONDispersive spectrometers from McPherson Inc. feature expanded sensor compatibility to expand the range of wavelengths and detect mid- and long-wave IR light. The spectrometers measure and tune specific wavelengths of light, with user-specific diffraction gratings for various applications. With increased utility for spectroscopy and imaging applications in chemistry, biology, aerospace, and defense, the devices are easy to use in the IR range because the devices readily couple to the exit focal plane. Grating groove density and optimum blaze wavelengths range from 0.2 to 20 µm. ...See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Jul/Aug 2023 IssueExtended InGaAs DetectorsHermetically sealed, surface-mount device-packaged 1.7- and 2.6-μm InGaAs PIN ATLAS photodiodes from Marktech Optoelectronics Inc. are designed for spacecraft, aerospace, medical, defense,...Photonics.com 10/13/2023FMCW Lidar Vision SystemsThe Eyeonic™ Vision System Portfolio from SiLC Technologies are vision detection systems that utilize FMCW lidar technology and can identify objects beyond a kilometer away while also providing...Photonics.com 2/9/2023Video Acquisition CardThe Lautrec LT-311 video acquisition card from Enciris Technologies features ultra-HD 4K up to 60 fps, four 12-G SDI inputs, 3D, 10-bit video processing, less than one-frame latency, PCIe 4xGen 2...Photonics.com 5/12/2022Frameless Servo MotorsThe TBM™2G series of frameless servo motors from Kollmorgen Corp. provides features that simplify the design of collaborative, surgical, aerospace, defense, and other robots.
